 Posted: Fri Nov 24, 2006 7:48 pm Post subject: Memory occupation |
 |
|
I have read all the guides about memory usage on linux, but it doesn't explain my memory usage.
I started the computer, logged into fluxbox(~90 MB directly after) through kdm. Left the computer for a couple of hours. When I came back I lock at conky and saw the memory usage was 543MB. How is this possible.
I am using

As you can see, I am not using anything that should use that amount of memory. Can anyone explain this to me?
Daily usage is usually around 550 - 900 MB when using firefox and azureus ... But now I have just logged into fluxbox. Seems kind of weird to me. Or does the kernel use some otherworldly precognition and read often used programs to ram in the similar way windows do with prefetch if I am not misstaken. But I reckon if it do that it would be displayed as buffered memory.
I have 2G ram so it doesn't matter, but I want to understand it. Otherwise conky and all the other program are worthless to me if I don't understand what they mean.
Hope someone can help. |

| Perhaps sorting the output of top by memory usage would be useful for diagnostic purposes, to do so start top then type 'M', sans quotes. |

Restarted the computer. After like 6-7 hours uptime the memory usage sky rocks again.

Did some test. Started an application that uses a lot of ram so the kernel will release memory. And closed it.

So it seams to release the extra memory. But why then isn't it showed as buffered or cached. |

It can be in several places. I recommend looking at:
cat /proc/meminfo
slabtop |

The harddrive starts to work for 15-20 sec and read something to slab. What does that mean.

| Your X server seems to be using a lot of memory too. Run xrestop to see which clients are using a lot of X memory. |

X has two screens, lcd 1440x900 and to the TV, so that might contribute to X memory usage.
